Published in InterConnection Technology, October 1992 Mr. Michael A. Baxter, B.S.E.E. Dr. Edward P. Sayre, P. E. Abstract The accurate prediction of backplane impedance values is an important step in the design, simulation and performance evaluation of backplanes for high performance digital systems. For example, specific knowledge of the impedance and propagation delay in FutureBus based designs for various conditions of loading of the backplane bus is critical to the prediction of timing relationships as well as the achievement of the "clean" incident wave switching required by FutureBus device designs. This paper provides the theoretical justification for the application of the backplane capacitive loading formulas in determining impedance and propagation delay and illustrates their use with a design case study. The results are correlated to the more exact mixed transmission line and discrete component SPICE simulated backplane model results and measurements. The paper closes with some innovative applications of the Scope54 automated measurement tool for quality control, parasitic capacitive characterization and on-screen comparisons of FutureBus backplane simulations and validations. ->This paper is available from NESA for $15.00 to cover management costs.
